    'https://api.dexpaprika.com/networks/sei/pools/search?order_by=volume_usd_24h&sort=desc&limit=5'
)
const { results } = await res.json()
for (const pool of results) {
    console.log(pool.dex_name, Math.round(pool.volume_usd_24h))
}

# top Sei pools by 24h volume — no key, no signup
import requests

pools = requests.get(
    "https://api.dexpaprika.com/networks/sei/pools/search",
    params={"order_by": "volume_usd_24h", "sort": "desc", "limit": 5},
).json()["results"]

for pool in pools:
    print(pool["dex_name"], round(pool["volume_usd_24h"]))

Streaming: stop polling Sei

Open one SSE connection and we push token prices and per-block pool reserve deltas as Sei state changes — the only push-based reserves feed on the market. Poll loops re-fetch unchanged state and still miss mid-block moves; push delivery makes the gap between on-chain state and your app the network round-trip, nothing else.

# push: live WSEI price ticks on Sei — one connection, no polling
curl -N "https://streaming.dexpaprika.com/sse/prices?chain=sei&address=0xe30fedd158a2e3b13e9badaeabafc5516e95e8c7&method=token_price"

# push: per-block reserve deltas for WSEI pools
curl -N "https://streaming.dexpaprika.com/sse/reserves?chain=sei&address=0xe30fedd158a2e3b13e9badaeabafc5516e95e8c7&method=token_reserves"
